Description

Control device and control method for electric vehicle
Technical Field
The present disclosure relates to a control device and a control method for an electric vehicle having a power receiving unit capable of receiving power in a non-contact manner from a power supply facility provided on a travel road.
Background
Japanese patent laid-open No. 2013-200247 discloses a navigation device that retrieves and displays a traveling route of a vehicle having a power receiving unit capable of receiving power from a power supply apparatus provided on a road in a non-contact manner. The navigation device searches for and displays the shortest route to the destination and a route leading from a power supply facility to the destination while receiving power from the facility in a non-contact manner through a road on which the facility is installed. The user can select a travel route that meets his or her own purpose.
Disclosure of Invention
In the case where a vehicle travels above a contactless power feeding device provided on a road and thus a physical power feeding condition for performing contactless power feeding from the device to the vehicle is established, if power feeding is performed unconditionally, power feeding is forcibly performed even if, for example, the power feeding fee or the power feeding unit price does not meet the desired amount of money of the user, and therefore, there is a possibility that the convenience of the user is impaired.
The present disclosure has been made to solve the above-described problems, and an object of the present disclosure is to perform road power reception without impairing convenience of a user in an electric vehicle capable of receiving power from a road in a non-contact manner from a device provided on a traveling road.
(1) The control device of the present disclosure is a control device of an electric vehicle having a power receiving unit capable of receiving power from a device provided on a travel road in a non-contact manner, and includes: a memory that stores a user-desired condition that is a condition in which a user of the electric vehicle desires to perform road power reception, which is power reception from the device by the power reception unit; and a processor coupled to the memory. The processor controls the power receiving unit so as to suppress road power reception when a physical power supply condition from the device to the power receiving unit is satisfied and a user-desired condition stored in the memory is not satisfied.
In the above configuration, when the physical power feeding condition from the device installed on the traveling road to the power receiving unit is satisfied but the user-desired condition is not satisfied, the road power reception is suppressed. This suppresses the power reception on the normal road from being forcibly performed when the user's desired condition is not met. As a result, in a vehicle capable of receiving power from a road, power can be received from a road without impairing convenience of a user.
(2) In one embodiment, the processor prohibits the power reception on the road or reduces the power reception amount of the power reception on the road to be smaller than that in a case where the physical power supply condition is satisfied and the user desired condition is not satisfied.
In the above configuration, the road power reception can be suppressed by prohibiting the road power reception or reducing the power reception amount of the road power reception.
(3) In one embodiment, the device further includes a port to which information of the device is input. The information of the device includes information on the cost or unit price of the power supplied from the device. The user desired condition includes a condition that the cost or unit price of the electric power supplied from the apparatus is less than a predetermined value.
In the above configuration, it is possible to suppress road power reception when the cost or unit price of the power supplied from the device is higher than the desired amount of money of the user.
(4) In one embodiment, the processor reduces the power receiving amount of the road power received when the physical power feeding condition is satisfied and the user-desired condition is not satisfied, the higher the cost or the unit price of the power supplied from the device.
In the above configuration, the amount of power received by the road can be suppressed in accordance with the cost or unit price of the power supplied from the power supply facility.
(5) In one embodiment, the electric vehicle includes a battery (battery) for running that is charged with electric power received by the power receiving unit. The user-desired condition includes a condition that the amount of charge in the battery is less than a predetermined value.
In the above configuration, road power reception can be suppressed when the amount of power stored in the battery exceeds a predetermined value. This makes it possible to suppress deterioration of the battery due to the road power reception maintaining the battery capacity high as desired by the user.
(6) In one embodiment, the information processing device further includes a port to which information of the device is input. The information on the equipment includes information on CO2 (carbon dioxide) emission during power generation of the electric power supplied from the equipment. The user desired condition includes a condition that the CO2 emission amount is less than a predetermined value.
In the above configuration, it is possible to suppress road power reception from a facility whose CO2 emission amount during power generation exceeds a predetermined value. This makes it possible to suppress road power reception using power with a large amount of CO2 emission during power generation, in accordance with the demand of a user who is highly conscious of global environmental protection.
(7) In one embodiment, the processor inquires of the user whether the road power reception can be executed when the physical power supply condition is satisfied and the user desire condition is satisfied, and executes the road power reception when a response indicating that the road power reception is to be executed is made to the inquiry. The processor suppresses the road power reception without inquiring the user as to whether the road power reception can be executed when the physical power supply condition is satisfied and the user expectation condition is not satisfied.
In the above configuration, when the physical power feeding condition is satisfied and the user desired condition is satisfied, the user is further asked separately whether or not the road power reception can be executed, and the road power reception that more appropriately reflects the user's desired condition can be performed. When the physical power feeding condition is satisfied but the user desired condition is not satisfied, the inquiry to the user is not made and the road power reception is suppressed. Therefore, the number of inquiries to the user can be reduced as compared with a case where the inquiry is always made to the user when the physical power supply condition is established.
(8) The control method of the present disclosure is a control method of an electric vehicle having a power receiving unit capable of receiving power in a non-contact manner from a device provided on a travel road, including the steps of: acquiring a user expectation condition, which is a condition that a user of the electric vehicle desires to perform road power reception by a power reception unit from a device; and controlling the power receiving unit so as to suppress road power reception when the user-desired condition is not satisfied although the physical power supply condition from the apparatus to the power receiving unit is satisfied.
In the above configuration, the same operational effects as those of the control device of the above (1) can be obtained.
The above and other objects, features, aspects and advantages of the present invention will become apparent from the following detailed description of the present invention, which is to be read in connection with the accompanying drawings.

Detailed Description
Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In the drawings, the same or corresponding portions are denoted by the same reference numerals, and description thereof will not be repeated.
< System construction >
Fig. 1 is a diagram schematically showing an example of the overall configuration of a vehicle management system 100 according to an embodiment of the present disclosure. The vehicle management system 100 includes a plurality of vehicles 1, a server 2, and a plurality of user terminals 3.
Each of the plurality of vehicles 1 is an electric vehicle mounted with a battery for running, and is, for example, an Electric Vehicle (EV), a Hybrid Electric Vehicle (HEV), or a plug-in hybrid electric vehicle (PHEV). Each vehicle 1 is configured to be able to receive power from a power supply facility 9 (see fig. 3 and 4) provided on a road surface of a travel road in a non-contact manner. Hereinafter, the non-contact power reception from the power supply device 9 is also referred to as "road power reception". The detailed configuration of the vehicle 1 will be described with reference to fig. 2 and 3.
The server 2 manages a plurality of vehicles 1. In addition, the server 2 holds the latest road information, and holds information (information such as power supply specifications, installation position, power supply unit price, and the like) about the power supply apparatus 9. With regard to the detailed configuration of the server 2, description will be made with reference to fig. 2.
Each of the plurality of user terminals 3 is a terminal operated by a user of the vehicle 1, and is, for example, a smartphone. The user can input the destination of the vehicle 1 and search for the travel route of the vehicle 1 by operating the user terminal 3. The vehicle 1, the server 2, and the user terminal 3 are configured to be capable of bidirectional communication via a network such as the internet.
Fig. 2 is a diagram showing the configuration of the vehicle 1 and the server 2 in more detail. The vehicle 1 includes an ECU (Electronic Control Unit) 11, a navigation system 13, and a communication module 14. The ECU11, the navigation system 13, and the communication module 14 CAN communicate with each other via an on-vehicle Network 15 such as a CAN (Controller Area Network).
The ECU11 includes a processor 111 such as a CPU (Central Processing Unit), a Memory 112 such as a ROM (Read Only Memory) and a RAM (Random Access Memory), and an input port P connected to the in-vehicle network 15.
The processor 111 is connected to the memory 112 and configured to execute predetermined arithmetic processing described in a program. The memory 112 stores programs executed by the processor 111. In addition, the memory 112 temporarily stores data generated by execution of the program in the processor 111 and data input from the in-vehicle network 15 to the input port P.
The processor 111 controls each device in the vehicle 1 so that the vehicle 1 is in a desired state based on detection values of various sensors (not shown) and programs and data stored in the memory 112. Further, the processor 111 generates various kinds of information exchanged with the server 2.
The navigation system 13 guides the travel route of the vehicle 1. The navigation System 13 includes a processor, a memory (both not shown), a GPS (Global Positioning System) receiver 131, and a display 132 with a touch panel.
The GPS receiver 131 determines the position of the vehicle 1 based on electric waves from artificial satellites (not shown). The navigation system 13 executes various navigation processes (search for a travel route, etc.) using the position information (GPS information) of the vehicle 1 determined by the GPS receiver 131.
The display 132 displays various information and accepts various operations by the user. More specifically, the display 132 displays the current position of the vehicle 1 and the set position of the power supply apparatus 9 on a road map around the vehicle 1. Further, the display 132 receives an operation of the user to select the travel route of the vehicle 1.
The Communication Module 14 is an in-vehicle DCM (Data Communication Module), and is configured to enable bidirectional Communication between the ECU11 and the server 2.
The server 2 includes an application server (application server) 21 and a database server (database server) 22. The database server 22 includes a vehicle information Database (DB) 221, a road information Database (DB) 222, and a charging information Database (DB) 223.
The application server 21 collects position information (GPS information) and SOC (State Of Charge) information Of each Of the plurality Of vehicles 1. These pieces of information are periodically transmitted from each vehicle 1 to the server 2. The application server 21 stores the collected information in the vehicle information database 221. The vehicle information database 221 also stores information on the frame number (type of vehicle, style)), model year (year), model (model), specification, and state (for example, the deterioration state and full charge capacity of the battery) of each vehicle 1. The application server 21 may acquire a travel history of each vehicle 1, more specifically, data relating to power consumption measured while each vehicle 1 travels, for each travel condition (travel route, date, day of the week, weather, air temperature, etc.) and store the data in the vehicle information database 221.
The road information database 222 stores road information. The charging information database 223 stores information (hereinafter also referred to as "road equipment information") about the power supply equipment 9 installed on the traveling road. The road equipment information includes information on the power supply specification (e.g., power supply capacity, etc.), installation location, power supply cost, and power supply unit price of the power supply equipment 9, as well as information on the presence or absence of a failure of the power supply equipment 9, CO2 emission amount of the power supply power at the time of power generation, and the like. The information on the CO2 emission amount may be a value of the CO2 emission amount itself or a renewable energy ratio. The renewable energy ratio is a ratio of electric power generated by renewable energy (sunlight, wind power, geothermal heat, etc.) with a low environmental load in the entire generated electric power. Carbon dioxide is hardly emitted when power is generated using renewable energy. Therefore, the renewable energy ratio is a value related to CO2 emission amount at the time of power generation.
Further, the road may be newly created or changed in shape. In addition, there may be a case where the power supply apparatus 9 is newly installed or an existing power supply apparatus 9 is discarded. Further, the power supply cost, the power supply unit price, and the renewable energy ratio of the power supply apparatus 9 may be changed. Therefore, the information stored in the road information database 222 and the charging information database 223 is periodically updated to the latest state by the manager of the server 2.
The road equipment information and the like stored in the server 2 are transmitted to the vehicle 1 at predetermined timing and input to the input port P of the ECU 11. The road equipment information and the like input to the input port P are stored in the memory 112 and used for calculation by the processor 111.
< road power receiving >
Fig. 3 is a diagram schematically showing an example of the configuration of the vehicle 1 and the power supply apparatus 9. In addition to the configuration shown in fig. 2, vehicle 1 includes a battery 163, an inverter 164, a motor generator 165, and a power receiving unit 166.
The secondary battery 163 is a battery pack including a plurality of battery cells (cells). Each battery cell is a secondary battery such as a lithium ion battery or a nickel hydrogen battery. Battery 163 is a battery for running that supplies electric power for generating driving force of vehicle 1 to motor generator 165. Battery 163 stores electric power generated by motor generator 165. The battery 163 is provided with a voltage sensor and a current sensor (both not shown) for the ECU11 to calculate the SOC of the battery 163.
Inverter 164 converts the dc power stored in battery 163 into ac power, and supplies the ac power to motor generator 165. Further, inverter 164 converts ac power (regenerative power) from motor generator 165 into dc power, and charges battery 163 with the dc power. Inverter 164 converts the ac power received by power receiving section 166 into dc power, and charges battery 163 with the dc power.
Motor generator 165 receives the electric power supply from inverter 164 and applies a rotational force to the drive wheels to cause vehicle 1 to travel.
In the example shown in fig. 3, the power receiving unit 166 is disposed on the lower surface of a floor panel (floor panel) forming the bottom surface of the vehicle 1. A power receiving coil is housed in the power receiving unit 166. The power receiving coil receives the power transmitted from the power supply apparatus 9 in a non-contact manner.
The power supply apparatus 9 includes a plurality of power transmitting units 91 to 96 and a controller 90. Although fig. 3 shows an example in which the number of power transmission units is 6, the number of power transmission units is not particularly limited, and may be larger.
The plurality of power transmitting units 91 to 96 are arranged in a line on the road surface. The plurality of power transmission units 91 to 96 include power transmission coils 911 to 961, respectively. The power transmission coils 911 to 961 are electrically connected to an ac power supply (not shown). Although not shown, a sensor (optical sensor, weight sensor, or the like) for detecting passage of the vehicle 1 is provided in each of the plurality of power transmission units 91 to 96.
The controller 90 determines the traveling position of the vehicle 1 based on the detection signals from the respective sensors. Then, the controller 90 supplies ac power from the ac power supply to the power transmission coil in the power transmission unit located above the vehicle 1 among the power transmission units 91 to 96.
More specifically, for example, when the vehicle 1 is detected above the power transmission unit 91, the controller 90 supplies ac power to the power transmission coil 911. Then, an alternating current flows through the power transmission coil 911, and an electromagnetic field is formed around the power transmission coil 911. The power receiving coil in the power receiving unit 166 receives power in a non-contact manner by the electromagnetic field. Thereafter, when the vehicle 1 is not detected above the power transmission unit 91, the controller 90 stops the supply of the ac power to the power transmission coil 911. By performing such a series of control for each of the power transmission units 91 to 96, it is possible to transmit electric power to the traveling vehicle 1 in a non-contact manner (road power reception).
< route of vehicle 1 >
Fig. 4 is a diagram showing an example of the travel route of the vehicle 1. In this example, three power supply apparatuses 9 each having a power supply specification capable of performing non-contact power supply to the vehicle 1 are provided on the travel route R1 from the current location of the vehicle 1 to the destination.
When the vehicle 1 is traveling from above the power supply facility 9 provided on the road on the travel route R1 and the power supply facility 9 and the vehicle 1 are in a state in which the road power reception can be performed normally physically (for example, a state in which the power supply specification of the power supply facility 9 conforms to the power reception specification of the power reception unit 166 of the vehicle 1 and both the power supply facility 9 and the power reception unit 166 are not in an overheated state but can operate normally), the physical power supply condition from the power supply facility 9 to the power reception unit 166 of the vehicle 1 is established.
The physical power feeding condition may include a condition that battery 163 of vehicle 1 is not in an overdischarge state or an overcharge state, in addition to a condition related to the specification and distance of power feeding apparatus 9 and power receiving unit 166 of vehicle 1 and a condition related to the temperature of power feeding apparatus 9 and vehicle 1. In either case, the physical power feeding condition is a condition that cannot be arbitrarily changed by the user of the vehicle 1, which is predetermined by the manufacturer or manager of the vehicle management system 100.
< suppression of road power reception based on user expectation >
If the physical power feeding condition from the power feeding apparatus 9 to the power receiving unit 166 of the vehicle 1 is satisfied, if the road power feeding is performed unconditionally, the road power feeding is forcibly performed even if, for example, the power feeding fee or the power feeding unit price does not meet the desired amount of money of the user, and therefore, the convenience of the user may be impaired.
Then, when the condition for physical power supply from the power feeding facility 9 to the power receiving unit 166 is satisfied but the condition for the user of the vehicle 1 desiring to receive power from the road (hereinafter also referred to as "user-desired condition") is not satisfied, the processor 111 of the ECU11 of the vehicle 1 according to the present embodiment controls the power receiving unit 166 so as to suppress power reception from the road. Thus, in the vehicle 1 capable of receiving power on the road, power can be received on the road without impairing the convenience of the user.
The user desired condition is set in advance by the user of the vehicle 1 and stored in the memory 112 of the ECU11 of the vehicle 1. As the user-desired conditions, conditions relating to cost, conditions relating to SOC, conditions relating to temperature, conditions relating to CO2 emission, and the like are assumed.
The condition related to the charge may include, for example, a condition that the charge or the unit price of the power supplied from the power supply apparatus 9 is smaller than the desired amount of money of the user. This can suppress road power reception when the cost or unit price of the power supplied from the power supply apparatus 9 exceeds the desired amount of money of the user.
In view of the fact that battery 163 is likely to deteriorate while the state in which the SOC of battery 163 is high continues, SOC-related conditions may include a condition that the SOC (amount of stored electricity) of battery 163 is smaller than a set value of the user in order to suppress deterioration of the battery. This can suppress deterioration of the battery 163 due to road power reception, as desired by the user.
In addition, when the SOC of the vehicle 1 at the time of arrival at the destination can be predicted, the condition relating to the SOC may include a condition that the predicted SOC at the time of arrival at the destination is lower than a set value of the user in order to suppress deterioration of the battery at the time of arrival at the destination.
In view of the fact that battery 163 is likely to deteriorate while the state in which the temperature of battery 163 is high and the SOC is high continues, the condition regarding the temperature may include a condition that the temperature of battery 163 is lower than a set value of the user in order to suppress deterioration of the battery. This can suppress deterioration of the battery 163 due to road power reception, as desired by the user.
The condition regarding the CO2 emission amount may include a condition that the CO2 emission amount of the power supplied from the power supply apparatus 9 during power generation is lower than a set value of a user. Further, it may be determined that the CO2 emission amount is lower than the set value of the user when the renewable energy ratio of the electric power supplied from the power supply apparatus 9 exceeds a predetermined value. This makes it possible to suppress road power reception using power with a large amount of CO2 emission during power generation, in accordance with the demand of a user who is highly conscious of global environmental protection.
Although it is assumed that the user desired condition includes various conditions as described above, the user desired condition is limited to at least a condition that the user can select.
Further, as a method of suppressing the road power reception when the user desire condition is not satisfied, the road power reception may be prohibited, or the power reception amount of the road power reception may be smaller than that when the user desire condition is satisfied.
Fig. 5 is a flowchart showing an example of a road power reception processing procedure. The flowchart is repeatedly executed, for example, at a predetermined cycle. Each step is realized by software processing performed by the processor 111 of the ECU11 of the vehicle 1. Note that a part of each step may be realized by software processing performed by the server 2. Each step may be realized by hardware such as an LSI (Large Scale Integration) disposed in the vehicle 1 or the server 2.
First, the processor 111 acquires road equipment information from the server 2 (step S10). As described above, the road equipment information includes information on the power supply specification, installation location, power supply cost, power supply unit price, CO2 emission amount, and the like of the power supply equipment 9.
Next, the processor 111 refers to the road equipment information and the like, and determines whether or not the physical power feeding condition from the power feeding equipment 9 to the power receiving unit 166 of the vehicle 1 is established (step S12). For example, as described above, the processor 111 determines that the physical power feeding condition is satisfied when the vehicle 1 travels above the power feeding facility 9 and the vehicle 1 are in a state where the road power reception can be normally performed physically.
If the physical power supply condition is not satisfied (no in step S12), the processor 111 ends the processing without executing the subsequent processing. Thus, road power receiving is not performed.
On the other hand, when the physical power supply condition is satisfied (yes in step S12), the processor 111 acquires the user desired condition stored in the memory 112 (step S14). Further, as described above, the user desired conditions include a condition relating to cost, a condition relating to SOC, a condition relating to temperature, a condition relating to CO2 emission amount, and the like.
The processor 111 refers to the road equipment information, the SOC and the temperature of the battery 163, and the like, and determines whether or not the user desired condition is satisfied (step S16).
If the user desire condition is satisfied (yes in step S16), the processor 111 performs road power reception (step S18).
On the other hand, if the user desired condition is not satisfied (no in step S16), the processor 111 suppresses the road power reception (step S20). As a method of suppressing the road power reception, as described above, the road power reception may be prohibited, or the power reception amount of the road power reception may be smaller than that in the case where the user expectation condition is satisfied.
The processing of fig. 5 is not necessarily executed repeatedly at predetermined intervals, and may be executed when the travel route of the vehicle 1 is set, for example. In this case, the processing shown in fig. 5 may be performed for each of the power supply apparatuses 9 arranged on the set travel route. However, since vehicle 1 does not actually run above power feeding facility 9 when the travel route is set, the physical power feeding condition may be determined in step S12 excluding the condition relating to the distance between power feeding facility 9 and power receiving unit 166 of vehicle 1, and road power reception may be permitted in step S18. When the vehicle 1 starts traveling and actually travels from above the power supply facility 9 that is allowed to receive power from the road, the power reception from the road may be performed.
As described above, the ECU11 of the vehicle 1 according to the present embodiment includes the memory 112 in which the user-desired condition is stored, and the processor 111 connected to the memory 112. The processor 111 controls the power receiving unit 166 so as to suppress road power reception when the physical power supply condition from the power supply apparatus 9 to the power receiving unit 166 is satisfied and the user desired condition stored in the memory 112 is not satisfied. This suppresses forced normal road power reception when the conditions desired by the user are not met. As a result, the vehicle 1 capable of receiving power from the road can receive power from the road without impairing the convenience of the user.
< modification 1 >
In the above-described embodiment, the road power reception is executed when the physical condition is satisfied and the user desired condition set in advance is satisfied.
In contrast, when the physical condition is satisfied and a predetermined user expectation condition is satisfied, the user may be asked whether or not road power reception can be performed.
Fig. 6 is a flowchart showing an example of a road power reception processing procedure according to modification 1. The flowchart shown in fig. 6 is obtained by adding steps S30 and S32 to fig. 5 described above. Since the other steps in fig. 6 (steps given the same reference numerals as those in fig. 5) have already been described, detailed description thereof will not be repeated here.
When the user expectation condition is satisfied (yes in step S16), the processor 111 inquires of the user of the vehicle 1 whether road power reception can be performed (step S30). For example, the processor 111 causes the display 132 to display a message asking the user whether road power receiving can be performed.
Next, the processor 111 determines whether or not the user has selected execution of road power reception in response to the inquiry of step S30 (step S32). For example, when the display 132 receives an operation for the user to select the execution road power reception, the processor 111 determines that the user has selected the execution road power reception.
Also, when the user selects to perform road power reception (step S32: YES), the processor 111 performs road power reception (step S18).
On the other hand, in the case where the user does not select execution of road power reception (no in step S32), the processor 111 suppresses road power reception (step S20).
In this way, when the physical power feeding condition is satisfied and the preset user desired condition is satisfied, the user is further asked separately whether or not the road power reception can be executed, and the road power reception that more appropriately reflects the user's desired condition can be performed.
In addition, the user is not always asked when the physical power feeding condition is satisfied, but asked when both the physical power feeding condition and the user expectation condition are satisfied. When the user-desired condition is not satisfied although the physical power feeding condition is satisfied, the power reception on the road is suppressed without making an inquiry to the user. Therefore, the number of inquiries to the user can be reduced as compared with the case where the inquiry is always made to the user when the physical power supply condition is satisfied.
< modification 2 >
When the vehicle 1 is in the traveling mode in which the road power reception mode allowing the road power reception is settable by the user, the above-described processing of fig. 5 or 6 may be executed when the road power reception mode is set.
Fig. 7 is a flowchart showing an example of a road power reception processing procedure according to modification 2. The flowchart shown in fig. 7 is obtained by adding step S40 to fig. 6 described above. Since the other steps in fig. 7 (steps given the same reference numerals as those in fig. 6) have already been described, detailed description thereof will not be repeated here.
The processor 111 determines whether or not it is in the road power receiving mode (step S40). If the vehicle is in the road power receiving mode (yes in step S40), the processor 111 executes the processing from step S10 onward.
On the other hand, if the vehicle is not in the road power reception mode (no in step S40), the processor 111 ends the processing without executing the processing from step S10 onward. Thus, no road power is received.
As described above, when it is not desired to perform road power reception in summer with a high temperature, for example, in order to suppress deterioration of battery 163, the road power reception mode is set to OFF (OFF) in advance by the user, and thus, even when both the physical power supply condition and the user desired condition are satisfied, the road power reception is not performed.
< modification 3 >
In the case where the method of reducing the amount of power received by the road is adopted as the method of suppressing the power received by the road when the user's desired condition is not satisfied, the amount of power received by the road may be reduced as the cost or the unit price of the power supplied from the power supply facility 9 is higher. This can suppress the amount of power received by the road, depending on the cost or unit price of the power supplied from the power supply facility 9.
The embodiments of the present invention have been described, but the embodiments disclosed herein are not intended to be limited to the embodiments shown in all aspects. The scope of the present invention is indicated by the claims, and all changes that come within the meaning and range of equivalency of the claims are intended to be embraced therein.
